Beyond the famous lookouts, San Luis Obispo County is full of quieter trails — waterfall canyons, oak-shaded ridges, and coastal bluffs where you can still find parking. Here are six worth knowing, with the practical details.
Reservoir Canyon Trail
San Luis Obispo · trailhead off Highway 101 North near Cuesta Grade · ~5 miles out-and-back, moderate to difficult
The local favorite for a reason: a roughly 20-foot waterfall and a small cave along the way, best after winter rains. Bring lots of water and sturdy shoes — parts are exposed and rocky. The trailhead lot is small, so arrive early on weekends.
Bishop Peak
San Luis Obispo · 787 Patricia Drive · 3.8 miles round trip, 1,145 ft of climbing
The county’s most recognizable summit, and worth it on a weekday morning before the crowds arrive. The Patricia Drive lot fills by 9 AM on weekends. From the top, views stretch from Morro Bay to the Irish Hills.
Felsman Loop
San Luis Obispo · Patricia Street trailhead area · ~2 miles, easy to moderate
A gentle loop with wildflowers in spring — a good pick for families or a quick evening walk. It shares the same Patricia-area parking as Bishop Peak.
Pismo Preserve
Pismo Beach · stacked loops, choose your distance
Miles of trails through coastal hills with ocean views around nearly every bend. The preserve lot can fill on clear weekends — go early and check the trail map at the kiosk.
Irish Hills Natural Reserve
San Luis Obispo · well-kept trails to big views
Usually quieter than Bishop Peak, with sweeping views from the top. Check current trailhead access before you go, and bring sun protection — much of the climb is exposed.
Johnson Ranch Trail
San Luis Obispo · rolling grassland, easier grade
Rolling grassland and oak with scenic views on a relaxed grade — a good alternative to the steeper summit climbs. Check a trail map for the current access point.
Trail conditions change with the weather — check recent trail reports before you go, carry more water than you think you need, and leave no trace.
